Hi there,

I just updated my calibre version to 0.7.5 and am now having a problem converting to EPUB. This happened with both LIT, HTML and EPUB->EPUB(just tried it to see what would happen). Here is my error:

ERROR: Conversion Error: <b>Failed</b>: Convert book 1 of 1 (Cut and Run)

My system is up to date as of yesterday.

Thanks!
